The vehicle can serve both high platforms and street-level stops; it has cabs at both ends, thus eliminating the need for turning loops.It was unique in Germany at the time for featuring thyristor chopper control and a contemporary design by Prof. Herbert Lindinger.

Technical parameters

A single unit has a length of 28.28 meters and a width of 2.4 meters, thus significantly increasing capacity compared to its predecessors. Up to 150 passengers can fit into a single car; in normal operations, two cars operate coupled together. The maximum speed is rated at 80 km/h, however it is not possible to sustain this speed on the Hanover network, so the de facto maximum speed is 70 km/h. The two DC motors are rated at 218 kW at 600 V each and can draw a maximum current of 900 A.

Cars 6206-6260 are microprocessor controlled, using an Intel 8085 and GTO thyristors.
